Okay this is kind of a strange question and btw thanks for merging threads for us moderators.

Ummm ok I would suggest...

-drink water throughout the day to stay hydrated
-don't spit your saliva out when you get cottonmouth; drink water/gatorade instead

The sour candy idea isn't a bad one either and also this is kind of important IMO:

When one smokes it changes one's perception of sound. So a lot of people end up talking quietly and not even realizing they are doing it, when they are high. You might try keeping this in mind, that weed alters your sense of sound, and do a sort of thought experiment with it.
